Abstract
A method of producing a hose in which a relatively inelastic material, such as ultra-high molecular weight polyethylene, is wrapped around an uncured hose. A rope is then wrapped about this combination with a cure wrap encircling the entire hose. During the curing process, the rope becomes embedded in the inelastic material forcing the underlying hose to be displaced. Once fully cured, the cure wrap and the rope are removed. The valleys where the rope was embedded into the hose provides flexibility which allows a hose with a highly protective outer coating to be flexible enough to reduce susceptibility to kinking during use, has a low coefficient of friction during dragging, is highly resistant to abrasion, and provides significantly improved chemical resistance compared to conventional hose constructions.
Claims11
A method of manufacturing a hose comprising the steps of:
- a) over an uncured hose body, placing a layer of inelastic material to form an uncured hose;
- b) wrapping a rope around said inelastic material;
- c) while curing said hose, pressing said rope against said inelastic material to a depth greater than a thickness of said inelastic material:
- and
- d) removing said rope from said cured hose.
A method of manufacturing a hose comprising the steps of:
- a) creating an uncured hose body over a mandrel;
- b) placing a layer of inelastic material over said uncured hose body to form an uncured hose;
- c) wrapping a rope around said inelastic material;
- d) placing a layer of cure wrap over said rope and said inelastic material;
- e) curing said hose, said layer of cure wrap shrinking thereby pressing said rope against said inelastic material to a depth greater than a thickness of said inelastic material:
- f) removing said layer of cure wrap after the step of curing said hose;
- and
- g) removing said rope from said cured hose.
A method of manufacturing a pliable hose comprising the steps of:
- a) creating an uncured hose assembly on a mandrel, said uncured hose assembly having an uncured hose body and a layer of inelastic material forming an uncured hose, a rope wound there around, and a cure wrap;
- b) curing said hose, said layer of cure wrap shrinking thereby pressing said rope against said inelastic material to a depth greater than a thickness of said inelastic material:
- and,
- c) removing said cure wrap and said rope from said cured hose.
